MACHINE FOR MAKING METAL SASH.

SPECIFICATION forming part of Letters Patent No. 399,545, dated March 12, 1889.

Application filed June 12, 1888. Serial No. 276,341. (No model.)

To all whom it may concern:

Be it known that I, \VILLAR'D F. MILLs, a citizen of the United States, residing at Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful. Machine for Making Metal Sash, of which the following is a specification.

This invention has for its object the construction of a machine for forming metal sash for sectional glass, said sash being formed from a thin strip of metal, and resembling in crosssection a letter H turned over on its side, (thus, I one head of said sash being of two thicknesses of material, the other head of single thickness, and the stem between the heads of two thicknesses.

In the drawings forming a part of this s ieciiication, Figure 1 is a side elevation, parts being broken away; Fig. 2, a section on line 3 in 1, looking from a point at the right; Fig. 3, section on line 5 5, looking from a point at the right in said Fig. 1; Fig. 4, section on line (3 (5 in Fig. 1, looking from a point at the right; Fig. 5, a section on line I i in Fig. 1 and line 1. 1 in Fig. 7; Fig. 6, a section on line 2 2 in Fig. 1; Fig. 7, plan of Fig. 5 and like parts in Fig. 1; and Fig. 8 is an end elevation of lettered parts in Fig. 1, looking from a point at the right.

Referrin g to the lettered parts of the drawings, P is the table upon which the several parts of the machine are attached.

In Fig. 1, a is a roll of a narrow strip of sheet-brass or other suitable metal capable ol. being bent into proper form, as will appear below.

I will now proceed. to describe the construction of the machine in conjunction with the operation.

The roll of brass or metal, 0, is on a windlass, for convenience, mounted in bearings at the top of brackets 1. In front of the windlass a bracket, 3, provided with a block, '21,

having a V-shaped groove in the upper side. At I is a casting in said groove of a size to form a V-shaped recess between the groove of the block a and the lower exterior of said casting. The casting I is laterally flanged each way on top. Screws 7 screw down through these flanges and into the block it. There is a nut, 9, on each screw. By turning the screws farther in or out the space through which the sash passes can be changed in size, and by turning one nut, or both, to proper points on the screws the sash material will be truethat is, both sides of the V-shaped strip will be of a height or at least accu rate enough. The reason is, that the upper edges of the V metal pass just beneath these nuts 8. I take the free end of the strip of metal 0, and bend the edges toward each other and insert it through the V-shaped recess, and thence into the groove 6 of roller A, Figs. 1 and 2, and beneath the wheel D in said recess. It should be here stated that two grooves, c, and two wheels, I), are shown in Fig. 2 simply to show that different-sized sash may be made with the machine, as will appear obvious from the diflierence in size of these parts in Fig. 2; but, so far as this description is concerned, only the use of one groove and wheel is described. This explanation also holds good as to the duplication of the peripheral grooves c in rollers C in Fig. 3; but, to return, the roller-A and wheel I) have bearings in the brackets i I, Fig. 2, and the roller A has a crankshaft or power-shaft, (7. The roller A and wheel D feed the strip of metal 0 on its way through the machine.

The effect of running the metal through the space between the groove 6 and the wheel I) is to make the metal angular incross-section, instead. of V form, thus adding another progressive step toward the final formation of the sash. The strip of metal next enters between the ends of the clamp-bar S, Figs. 1,5, and 7. These bars are so fixed as to leave a space between their lower edges and the bed-piece 21, mounted on the bracket 6. Thus a i-shaped recess is formed, through which the ]-shaped metal is drawn, which action pinches down and inward the sides of the shaped metal, and forms it into a L shape of double thickness, Fig. 5, at c. The metal then passes between rollers C E and into the groove Z of the roller 0, which compresses the folded metal still closer and feeds it onto the next part of the machine. The rollers (l E have suitable bearings in brackets 5, Fig. 3, on table P, Fig. 1. The rollers A C are gear-connected, so as to revolve in unison by the gears l3 13. The metal of double thick= ness then passes 011 through a L;shaped recess in block V and beneath the roller b, Fig. 8. Before entering beneath the roller 1) the double stem of the sash is separated by a tool, .1", located between the roller 1) and the roller 0. This tool consists of a bar having a pendent prong, 7, which enters between the two parts of the stem, and shoulders at right angles to said prong 7, which turns the metal each way laterally, as in Fig.4. The roller 7) completes the shaping of the upper flanges or head of the I-shaped sash by compressing it at right angles, as in Fig. 8. Said Fig. 8 shows the form of the sash as complete in cross-section.

The recess in the bracket '0 may be made smaller or larger, so as to secure the proper compression of the roller 1) by means of the sliding wedge if, forming a bed plate, and which wedge is operated by the screw y, Fig. 1. If preferred, the strip of metal may be operated upon by each part of the machine separately by having said several parts in separate machines, and this is especially true in regard to the last part in which the tool 00 and roller 1) appearthat is, after the strip 0 has passed through rollers O E. It may then be treated by the tool a: and roller Z) and recess in block V in a separate machine; but I find the best results are attained by having each part of the machine for the several parts of the work located one after the other on a common table or support, as here shown.

Having thus described my invention, what I claim is v 1. The combination of a suitable support, a bracket thereon having a V-shaped recess for the strip of metal to pass through, a roller having an angular peripheral groove and a wheel above in said groove, between which groove and wheel the metal passes, a bracket having a -shaped recess, through which the metal next passes, and a roller having a peripheral groove and a roller below, between which rollers the -shaped metal strip passes, substantially as set forth.

2. The combination of a suitable support, a bracket thereon having a V-shaped recess for the strip of metal to pass through, a roller having an angular peripheral groove and a wheel above in said groove, between which wheel and groove the metal strip passes, a -shaped recess, through which the metal strip next passes,-two rollers, between which the -shaped metal passes, one having the peripheral groove to receive the stem of the metal strip, the tool having the prong and shoulders for separating the parts of the double stem and turning them over, and the bracket and roller having the I-shaped recess between them, through which the metal finally passes, substantially as set forth.

3. The combination of a suitable table or support, a reel on which the metal strip is wound, a V-shaped recess for the metal to pass through, the grooved roller, and wheel in said groove, the L-shaped recess, through which the l |shaped metal passes, the rollers, one of which. is grooved and between which the -shaped metal passes, and the tool having the prong and shoulders, and the end bracket having the block and roller with. I shaped recess, through which the sash is drawn in its completed condition, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two witnesses.
